How can I limit the number of pages a user can create in a page of a specific type.

One of my category pages should only allow two child pages of a SPECIFIC type. I.e. The category page "Gender" should only be allowed two pages - so if a user have created the pages BOY and GIRL, they should be denied to create another "GenderPage" in the category

I tried to do something like

function canCreate() {
$child = DataObject::get("BoyPage","ParentID = ".$this->ParentID);
if($child->Count() > 1) return false;
return true;
}

but it seems like the parentID & ID fields are uninitialized

I think this will be because canCreate() is called before write() which populates these fields. Maybe parentID is available in $_REQUEST to use although it could be that canCreate isn't even called with on and Page object.
